This  latter  work  was  performed  by  Mr.  C.  M.  Palmer,  a  senior 
student  of  the  School  of  Pharmacy. 
The  examination  of  the  chloroformic  and  alcoholic  extractions  was 
carried  beyond  the  report  made  in  this  communication,  but  the 
interesting  work  is  not  yet  completed,  and  will  be  made  the  subject 
of  another  paper  at  the  coming  meeting  of  the  society. 
RECENT  LITERATURE  RELATING  TO  PHARMACY. 
SYNTHETIC  REMEDIES. 
Lactophenin,  according  to  Dr.  George  Thompson  [Universal 
Medical  Journal,  August,  1897),  possesses  several  advantages  over 
phenacetin.  As  is  well  known,  lactophenin  is  a  definite  chemical 
compound,  differing  from  phenacetin  by  containing  lactic  instead  of 
acetic  acid.  The  substitution  of  lactic  acid,  it  is  claimed,  overcomes 
almost  entirely  the  possibility  of  cardiac  depression  or  the  conver- 
sion of  haemoglobin  into  methaemoglobin,  an  attribute  only  too  fre- 
quently met  with  in  antipyrin,  acetanilid  and  phenacetin.  As  an 
analgesic  it  is  equal,  according  to  the  author,  to  the  best  pain  reliever 
in  the  materia  medica,  and  it  may  be  given  with  confidence  in  neu- 
ralgia from  any  other  cause  than  traumatic. 
Thiol  has  been  found  by  Dr.  Wirz  [Dent.  Med.  Wochenschrifti 
July,  1897)  to  be  superior  to  ichthyol  in  some  hundreds  of  cases.  It 
is  odorless,  so  that  patients  who  could  not  bear  the  odor  of  ichthyol 
improved  under  thiol.  It  can  be  used  in  every  description  of  inflam- 
mation, in  carbuncles,  erysipelas,  typhilitis,  furunculosis,  etc.  The 
best  results  are  obtained  with  liquid  thiol  as  supplied  by  the  manu- 
facturers, not  by  that  prepared  from  powdered  thiol  with  an  addi- 
tion of  water.
